Head gasket

I have a 1995 four runner 3rd gen with a 3.4 motor and tranny in it. It's a 5 speed. For the past couple weeks I've been smelling this burning oil smell inside the cab. I looked at the back of the engine and notice that there is a little bit of oil. Are my head gaskets leaking and or going to blow. If it blows does it cause a lot damage. Do I need to replace the head gaskets soon and what would cause them to leak oil? Thank you

Answering this kind of question from behind a keyboard is difficult, not seeing the car. But I can address part of it. If a head gasket blows, yes, it's serious and expensive. If the car is high mileage and been overheated, then it is likely that the head gasket is blown. Pull the dipstick and if the motor oil looks like chocolate milk, even more evidence of same.
